Q. Paul di Resta, you've been confirmed as test and reserve driver? When did it sink in that you would be part of Formula 1 this year?
Paul di Resta: It's been quite a long wait from Jerez at the beginning of December last year when we did the test. We've been talking and things have been progressing, and finally it was announced. That was the true point when you kind of confirm to yourself that that's what you're going to be doing as a job this year. And it's a very exciting opportunity. I have to thank Force India for giving me the chance to do it, and hopefully we can build a good relationship for many years to come.
Q. Tell us about your program.
PDR: It is going to be a very busy year. Firstly with Force India, they're going to be doing something completely different to other teams. I'm going to be running on quite a number of Friday free practice sessions during 2010, so it's going to be a good opportunity to get working in a Formula 1 environment at the race weekends, and also get involved in different situations.
I'm sure it's going to be the normal program that a race driver would undertake, and it just gives me a better idea and a better understanding of the environment that I'm in. I'm looking forward to it. It's going to be something new to me but I'm hoping to try and build on this for a race seat in 2011.
Q. How have you prepared for this role, do you feel like part of the team?
PDR: Yeah, I must say the team makes you feel very welcome. I've spent quite a few days there in the past couple of weeks. It's moving on, and the more and more it goes on, the more and more comfortable that you feel. I've been looking forward to it since I was confirmed.
Q. Mark Smith, this is the first time you've tested, how was it?
Mark Smith: Today is really about verification of many things. When you design a car you're obviously working with lots of models, whether it's a wind tunnel model, CFD, simulation tools, tire models, chassis models, suspension models...all of these models are the tools that we use to design the car. The first time it runs effectively on a circuit we try to validate those models.
Today has been really about 'Does the car have the weight distribution that we designed it to have? Does it have the aero balance? Is the thermal balance where we expected it to be?' And working through those kinds of things along with all the usual systems checks – does the car function correctly? That's really what today was about.
Q. What are the main differences with the new car?
MS: The biggest obvious difference is the length of the car and the wheelbase, which is a function of the ban on refueling. That's not an inconsiderable increase in wheelbase, which is evident visually. That's the biggest difference. In terms of aerodynamics it's a development of the themes that we worked with last year. Obviously the integration of the double diffuser from the outset of the design is probably a key factor as well.
Q. What is the development plan?
MS: The development program really hinges around the whole philosophy of trying to go to the first race with the quickest car we possibly can. That's tied up with a whole host of logistical factors. Not going to Valencia for instance so we could keep the car in the tunnel for a few more days, and making sure that we've got the right quantity of the right parts at the first races.
For Bahrain, the car has a reasonable update from the car that we're running today, in terms of diffuser, front wing, the usual aero parts, so we're looking forward to that. We'll go to Melbourne with another step, so we'll hopefully start further forward than we started last year, but we'll keep moving forward as quickly as we can.
